PERM UTATlON-LOCK.

SPECIFICATION forming part of Letters Patent No. 641,501, dated January16, 1900.

Application filed April 24,1899- To aZZ whom, it may concern.-

Be it known-that I, GEORGE WILLIAM DIL- LAWAY, of Muscatine, in thecounty of Muscatine and State of Iowa, have invented cer* tain new anduseful Improvements in Permutation-Locks; and I hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, which form part of thisspecification. I This invention is an improvement in permutation-locks;and it consists in the novel combinations and constructions of partshereinafter claimed.

The accompanying drawings illustrate the best form of look now known tome embodying my invention; but as the form of the look when theinvention is once known can be varied in details I do not herein limitmyself to the specific constructions of lock shown in the drawings andhereinafter described.

Referring to the drawings, Figure 1 is a top plan of the lock, partlybroken away. Fig. 2 is a rear view thereof, partly broken away. Fig. 3is a detail vertical section on line 3 3, Fig. 2. Fig. 4 is a similarvertical section on line 4 4, Fig. 2. Fig. 5 is a similar section online 5 5, Fig. 2. Fig. 6 is a detail rear perspective. Fig. 7 is adetail of the handleguiding device. Fig. 8 is a detail top plan view ofthe tumbler-holder and tumblers. Fig. 9 is an enlarged perspective viewof one of the tumblers. Fig. 10 is a detail sectional view of amodification.

Referring to the drawings, A designates the tumbler case or holder ofthe lock, which, as shown, consists of a rectangular block provided onits upper surface with two parallel series of tumbler guide-fingers a a,separated by a longitudinal groove (L The fingers Ct are preferablybeveled on their front edge, so as to facilitate entrance into the slotsbetween the fingers, and in each slot, between the fingers, is placed areversible tumbler B, which in the construction shown is rectangular inform, so as to fit easily in one of the slots between the adjoiningfingers, and each tumbler is provided on its upper edge witha notch b,which notch is nearer to one end of the tumbler than the other anddivides the upper surface thereof into a short or idle portion I) and along or looking portion b Phe Serial No. 714,230. (No model.)

idle portion may bear a number or letter or other indicating charactercorresponding to the number or-indicating character of the slot in whichit is to be placed-11. 6., indicating characters may be marked 011 theblock A beside the slots, or, preferably, may be made on a plateA,overlying the fingers a-and assist ing in retaining the tumblers inthe grooves. A plate A may also be placed across the fingers a for thesame purpose. If the tumblers are set so that all the locking portions bare in line with the front row of fingers a, as indicated in Fig. 3, thenotches b coincide with the groove a between the series of fingers a a,and when in this position the tumblers stand normally innon-lockingpositionthat is, not in position to prevent the unlocking ofthe device. If any one or more of the tumblers B are reversed, so thatthe locking portions 11 are in line with the fingers 00', parts 19 willthen project into the groove a as shown in Fig. 8, and such tumblerswill then be normally in looking position-that is, they would obstructthe groove a and prevent the descent of the lockin g bar or plate 0,hereinafter referred to. It is obvious, therefore, that any number ofthe tumblers B may be made the active or normal lockingtumblers byreversing them or turning them around so that the parts I) are in therear row of fingers a.

The locking bar or plate 0 stands normally over the groove a and untilthis plate can enter said groove the bolts will be looked, ashereinafter described. Of course so long as any locking portion 19 ofthe active tumblers projects into the groove a the locking-plate cannotenter the groove.

When any of the tumblers are in active looking position, as described,before the plate can enter the groove a it is necessary to push suchtumblers out of the way until their notches I) register with groove 0L2,and this is accomplished by means of a selector and pusher, which in theconstruction shown consists of a pin D, mounted on a slide D, guided ina slot E in a hinged or rocking plate E, that is pivoted just in frontof the block A, the slot E extending horizontally in front of the lineof tumblers, as shown, and by moving the slide D back and forth pusher Dcan be brought opposite any tumbler in any slot of the block, and thenby pushing plate E forward the pusher D is projected into the slotagainst the tumbler therein and pushes the tumbler backward, asindicated in Fig. 5. The slide D may be shifted by means of an arm Dattached to a gear D pivoted on a suitable stub-shaft D above the plateE, said arm having a slot (1, engaging a pin d on the slide, so as topermit the arm to reciprocate the slide back and forth as the gear D isoscillated. The gear D as shown, is operated by a pinion f, slidably butnot rotatably mounted on a shaft F, which is connected to a conical plugF, that has a cylindrical head F fitting in a cylindrical bore F in thewall of the safe or casing of the lock, the inner portion of the plugbeing tapered, as shown at f, and the inner portion of the bore in whichthe plug is contained being also tapered, as shown at F so that if saidplug is pushed too far inward it will jam in the bore, so that it willbe impossible to force it inward through the bore. The face of this plugat the exterior side of the wall of the lock (or safe-door to which itis applied) is connected to the stem g of an operating-handle G, whichmay be pushed outward by a spring G, interposed between the wall of thesafe and a disk H on the stem g, as shown in Fig. 5. This springnormally projects the handle G and disk l-I outward, thereby pulling theplug outward with it, the normal position of the parts being such thatthe face of the plug will be flush with the face of the safe.

The spring G and disk H are inclosed in a conical casin g h, resemblingan ordinary permutation-lock indicator, and on the handle G, exterior tothe disk H, is a conical plate G the edges of which are tapered inconformity with the taper of the casing h. The plate G may be kept closeto casing h by means of a band It on the casing, as shown, so that theplate can rotate with the handle, but has no longitudinal movementtherewith. The casing 7L or plate G or both, may be provided withindicating-marks, as shown, there being at least one mark for eachtumbler in the lock, and these marks being so located that the operatorcan by turning the handle G until a certain point on the plate Gregisters with some particular mark on the casing h bring the pusher Dopposite the slot containing the tumbler bearing the same mark. He canthen by pushing the handle inward cause the pusher to engage with suchtumbler and push the latter inward.

In the construction shown the inner end of the shaft F is looselyconnected to a hinged bar f which is hinged at its upper end, as shownat f while its lower bifurcated end f looselyengages or is connected tothe tilting plate E, so that when the handle G is pushed inward theplate E is rocked forward, throwing pusher D into one of the slots andpushing back the tumbler therein, as is evident from the drawings. Toenable this action to occur, the shaft and handle G are capable of bothrotary and longitudinal movement, the handle G being made angular, sothat it will rotate the plate G but can slide freely therethrough. Thedisk H is fixed to the handle G, so that it partakes of both movementsthereof, and this disk is provided with a controlling-finger H, which isadapted to enter one of a series of perforations H in the face plate ofthe lock or door to which it is attached, so as to prevent the rotationof the shaft F and handle Gwhen the lock is pushed inward and to alsoprevent the latter being pushed inward until the pusher D has beenshifted into exact position to engage with some one of the tumblers.

The locking-plate O in the construction shown is preferably suspendedvertically above the slot 0, by means of hinged arms 0. One of said armsC engages the bifurcated end I of a pivoted bolt-lockinglever I, whichis oscillated into unlocking or bolt-releasing position by the entranceof the locking-plate into the groove of and is thrown into lockedposition so long as said plate 0 is lifted and kept out of the groove.Of course this plate remains in lifted position orout of the groove solong as any locking-tumblers are in locking position or will be kept outof this groove if any of the non-locking tumblers are improperly shiftedin their slots, as might be done by any one attempting to tamper withthe locks, for if any one of the non-locking tumblers be shiftedbackward it will prevent the entrance of the locking-plate into thegroove even should the proper tumblers (which had been adjusted tonormally keep it out of the groove) be shifted into unlocking position,because it is necessary with my look not only that the locking-tumblersbe shifted into unlocking position, but that all the other non-lockingtumblers remain in their normal non-locking position. In other words, inmy look a certain number of tumblers can be selected as the normallocking tumblers and will normally stand in position to prevent theentrance of the locking-plate into this groove,while theremainingtumblers will normally stand in position to permit the plate toenter into the groove. This locking-plate, therefore, cannot enter thegroove until every one of the locking-tumblers are moved into unlockingposition, and if any one tampering with the lock displaces any of thenon-locking tumblers they will prevent the entrance of the locking-plateinto the groove, and although he may subsequently move all the normallocking-tumblers into unlocking position, yet he will not be able toopen the lock; but before it can be opened it will be necessary toreturn all the non-locking tumblers to non-locking position and thelocking-tumblers to locking position. This, however, can be easilyaccomplished by means of one certain setting-tumbler, (designated as Bin the drawings,) which setting-tumbler is provided with a notch Z) likethe others, adapted to register with the groove (F, but is provided witha rearwardly-projecting finger B which is adapted to engage anoscillating lever or levers J, pivoted on the top of block A in rear ofthe tumblers, said levers being adapted to engage with the push-plate J,which lies in rear of all the tumblers and will be pushed back by thedisplacement of any one of them, as indicated in Fig. 5. If, therefore,a mistake has been made in pushing any one of the tumblers, the operatorcan shift the pusher D in position to engage the setting-tumbler B,(determining this by a known mark on the index-plate G and when tumblerBis pushed backward its inner end operates the levers J, which in turnpush plate J forward toward the fingers a, throwing all the tumblersback into theiroriginally-set position. The first tumbler that isthereafterward displaced will force the plate J backward, and by sodoing will cause the levers J to return the tumbler B to originalposition. The plate J may be guided by pins J attached to block A andprojecting through perforations in the plate, as shown.

As a further precaution against the descent of the plate 0 and as ameans of providing a day-lock, I provide one of the tumblers withpositive means for controlling the rise and fall of the plate 0, even ifall the other tumblers be in unlocked position, so thatit will benecessary to actuate this particular tumbler after the permutationlocking-tumblers have been displaced. For this purpose I employ thetumbler B This is. provided with an upstanding finger 19 which (when thetumbler B is in normal position) stands above and across the slot a andobstructs the entrance of the locking-plate. The front end of thisfinger b however, is beveled, as at 12 and leads into a notch 6 which isadapted to register with groove a when the tumbler B is moved backwardby the pusher D and will permit the descent of the locking-plate it theother tumblers are all in proper unlocking position at the time. Thistumbler B is, moreover, provided with a rearwardly-projecting finger Bwhich when the tumbler is pushed inward engages the upturned end k ofabent rod K, that extends forward beyond the hinged plate E and has anupstanding finger 7a, which normally impinges against the front edge ofthis plate. When the tumbler B is pushed backward by the pusher D, itmoves rod K backward by the engagement of projection B with arm k,causing arm 76' to fol low up the plate E; but when plate E is pulledback to normal position by spring G and intermediate connections,thereby retracting the pusher, it causes arm 76' to pull rod K forward,and it,through arm it, pulls tumbler B forward, and then the bevel b onthe tumbler rides against a bevel C on the locking-plate and forces thelatter out of the groove a and holds it up out of the groove, the plateresting on arm b until the tumbler B is again displaced. By this meansthe locking-plate is positively raised, and in so doing the boltlockingdevices are thrown in position to positively prevent the unlocking ofthe bolts.

As shown, the locking-plate 0' stands over slot a and is weighted, as at0 so as to cause it to drop by gravity into the groove 0, when permittedbut,if desired,the tumbler B could be replaced by a tumbler 13 (see Fig.10,) which is provided with an inclined groove B", engaged by a pin 0 onthe locking-plate, so that this tumbler would move the lockingplatepositively into and out of the slot.

For convenience the tumbler carrying block A may be made removable, sothat it and the tumblers can he slid out from under the locking-plate topermit the tumblers to be set or rearranged at will and adjusted intonormal looking or unlocking position, according to the permutation -signdesired. As shown, the ends of block A are formed with dovetailedgrooves A, engaging dovetailed guides of, secured to the support for theblock, and when slid into position the face of the block abuts against aplate A'', by which the tumblers are all kept in alinement and preventedfrom going too far forward. The block may be detaohably secured inposition by means of the lever L and slot L or any other suitableattaching devices. The bar K may be detachably secured in a groove a inthe end of the block A, as shown, if desired.-

When the tumblers are in normal unlocking position, Fig. 3, theindex-marks thereon, on the portion b thereof are covered by the plate Abut when they are adjusted to normal locking position the indexcharacters thereon appear on the portion b projecting from beneath saidplate, so that by noting the characters appearing on the projecting endsof the tumblers the locking-tumblers will be known and can be selectedby the index and handle G. In unlocking it is not necessary thattheunlocking-tumblers be selected or shifted in any particular order. It isnecessary, however, that all the lockingtumblers shall first be pushedback before the day-lock tumbler B is pushed back, and it is furthernecessary that none of the other nonlocking-tumblers shall have beendisturbed. To look the safe, the handle is turned until the indexregisters with a mark corresponding to the setting-tumbler B, and thenis pushed back, whereupon all the tumblers are thrown into normalposition by the plate J, and the safe cannot be unlocked until they areproperly displaced under conditions just recited. However, if it isfrequently desired to open the lock during the day after it has beenonce opened the setting-tumbler should not be operated, as the othertumblers will remain in unlocking position until the settingtumbler ispushed back; but the tumbler B will then serve as the sole and temporarymeans of locking the plate.

To change the permutation, the block A, with the tumblers, can beremoved from its position and any number of tumblers desired can be madelocking-tumblers (which it will be necessary to shift before the lockcan be opened) by simply reversing them in their slots or by turningthem so that the parts 6 are in rear of the groove a and any tumblersthat are not to be locking-tumblers are left in position or turned sothat their parts 13 will be in front of the groove a It will thus beobvious that the tumblers can be changed from normal looking to normalunlocking position by simply reversing them or turning them aroundendwise in their grooves. Suppose, for example, that the permutation wasU S X. The tumblers U S X would be placed in their slots so that theparts 12 were at the rear of the groove a and then when the tumblers arein normal position it will be impossible for the plate 0 to enter thegroove until each one of these tumblers U S X have been pushed backwardby the pusher and none of the others disturbed. These three tumblers maybe pushed back in any order, and after they are pushed back it is thennecessary to push back the day-lock tumbler 13 whereupon the plate candescend. The tumbler B can then be used also as the day-lock, or bypushing back the setting-tumbler B the entire combination will have tobe operated to unlock the safe.

I have simply given an instance of a selection of three tumblers for thepermutation; but obviously any number might be employed, as desired; butI do not consider it advisable to select a very large number oftumblers, because of the double safety feature of the lock-to wit, thedisplacement of a wrong tumbler necessitating the resetting of theentire set before it can be opened.

I have shown the tumblers arranged in a straight series and operatedindirectly from the handle. In some forms of lock the pusher might beconnected directly with the handle and operated directly thereby and thetumblers may be arranged in a curved series vertically or horizontallyor concentric to the pusher, or in simple forms of lock the handle mightbe attached directly to the pusher and slide in a groove in front of thetumblers.

It is obvious that the invention is capable of modification andembodiment in various forms within the scope of my invention andembodying the essentials thereof, and therefore, While I consider theform which I have illustrated the best now known to me, I do not wish toconfine myself to the specific construction shown, but shall undertaketo here disclose the many modifications of the device which haveoccurred to me or may occur to others when the invention is make knownto them.
